Life can survive on much less water than you might think

"Follow the water" has long been the mantra of our scientific search for alien life in the Solar System and beyond. We continue seeking conditions where water can remain liquid either on a world's surface or elsewhere within a planetary body. This approach makes a lot of sense. Life as we know it requires water for the complex chemistry that enables growth and reproduction. Where there is water, we believe life has a chance.

To Agilkia... and beyond: Comet landing site is named

Will space historians one day say "Agilkia" with the same awe as they utter "Tranquility Base," where in 1969 Man first walked on the Moon?

A look at Virgin Galactic's feathering technology

The Virgin Galactic spaceship destroyed when it broke apart high over the Mojave Desert was designed to take tourists on a fleeting thrill ride through the lower reaches of space.

Many questions still unanswered in spaceship crash

Federal accident investigators have an early sense of what went wrong before an experimental spaceship designed to carry tourists beyond the Earth's atmosphere broke apart during a test flight. But they still don't know why the craft prematurely shifted its shape prior to the deadly crash.

Debris from downed spaceship found 35 miles away

Federal accident investigators say that tiny pieces of an experimental spaceship that broke up in flight have been found 35 miles from the main wreckage area.

NTSB reveals spaceship crash timeline, fingers lever

Investigators gave a precise timeline late Monday of the devastating Virgin Galactic spaceship crash, detailing exactly when a slowing mechanism was wrongly deployed, but said they could not determine who activated it.

Risk-taker Branson battles to protect Virgin brand (Update 2)

Richard Branson knows how to handle business setbacks, but he is now battling to protect the Virgin empire's image following the test flight crash of his flagship space tourism venture.

Branson pushes on with spaceship plan despite crash

Space tourism venture Virgin Galactic on Tuesday said it was pressing ahead with plans to build a second model of the SpaceShipTwo which crashed in the Mojave Desert last week.

Eye-catching space technology restoring sight

Laser surgery to correct eyesight is common practice, but did you know that technology developed for use in space is now commonly used to track the patient's eye and precisely direct the laser scalpel?

Why Rosetta is the greatest space mission of our lifetime

With only a week to go before the Rosetta spacecraft drops its Philae lander onto the surface of comet 67P, I wonder whether there will be another space mission in my lifetime that is so inspiring. Part of what has been so impressive is the length of time this mission has taken to finally get to the comet – 20 years since planning began (when I was still in high school), ten years since launch (when I was studying for my first degree). I feel very lucky that I am now employed as a space scientist at a time when all this work is coming to fruition.

How to land on a comet

Generally speaking, space missions fall into one of three categories:  difficult, more difficult, and ridiculously difficult.

Antares explosion investigation focuses on first stage propulsion failure

Investigators probing the Antares launch disaster are focusing on clues pointing to a failure in the first stage propulsion system that resulted in a loss of thrust and explosive mid-air destruction of the commercial rocket moments after liftoff from NASA's Wallops Flight Facility, VA, at 6:22 p.m. EDT on Tuesday, October 28.

Incredible fast-moving aurora captured in real time

Usually, videos that feature aurora are timelapse videos, in order to show the normally slow movements of the Northern and Southern Lights. But here are some incredibly fast-moving aurorae shown in real time, as seen by astrophotographer extraordinaire Thierry Legault. He was in Norway last week and said the fast-dancing, shimmering aurora were incredible.

Hi-SEAS and Mars Society kick off new season of missions

The Hawaii Space Exploration Analog and Simulation (aka. Hi-SEAS) – a human spaceflight analog for Mars located on the slopes of the Mauna Loa volcano in Hawaii – just kicked off its third research mission designed to simulate manned missions on Mars.

SDO sees a mid-level solar flare: Nov. 3

The sun emitted a mid-level solar flare, peaking at 5:40 p.m. EST on Nov. 3, 2014. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however—when intense enough—they can disturb the atmosphere in the layer where GPS and communications signals travel.

Less reward, more aversion when learning tricky tasks

We celebrate our triumphs over adversity, but let's face it: We'd rather not experience difficulty at all. A new study ties that behavioral inclination to learning: When researchers added a bit of conflict to make a learning task more difficult, that additional conflict biased learning by reducing the influence of reward and increasing the influence of aversion to punishment.

Humans could have an innate sense of probability, research shows

(Medical Xpress)—Is a sense of probability learned or innate? To find out whether probability is a subject that people must learn in school, Vittorio Girotto and colleagues at University IUAV of Venice tested rural Mayan villagers, with no formal education, on their knowledge of probability. They found that the villagers performed just as well on probability-related tasks as Mayan schoolchildren and Italian adults. The research appears in the Proceedings of the National Academy of Sciences.

Scientists see mechanism for spontaneous HIV 'cure' (Update)

French scientists claimed Tuesday to have found the genetic mechanism for a "spontaneous cure" in two HIV-infected men, proposing a new strategy for combating AIDS even as other experts urged caution.

Why does red meat increase the risk for cardiovascular disease? Blame our gut bacteria

New research provides details on how gut bacteria turn a nutrient found in red meat into metabolites that increase the risk of developing heart disease. Publishing in the November 4th issue of the journal Cell Metabolism, the findings may lead to new strategies for safeguarding individuals' cardiovascular health.

Type 2 diabetes, cardiovascular disease may share deep roots

(Medical Xpress)—Type 2 diabetes (T2D) and cardiovascular disease (CVD) appear to have a lot in common. They share risk factors such as obesity and they often occur together. If they also share the same genetic underpinings, then doctors could devise a way to treat them together too. With that hope in mind, scientists applied multiple layers of analysis to the genomics of more than 15,000 women. In a new study they report finding eight molecular pathways shared in both diseases as well as several "key driver" genes that appear to orchestrate the gene networks in which these pathways connect and interact.

Oxytocin levels in blood, cerebrospinal fluid are linked, study finds

For years, scientists have debated how best to assess brain levels of oxytocin, a hormone implicated in social behaviors. Now, researchers at the Stanford University School of Medicine have found the first direct evidence in children that blood oxytocin measurements are tightly linked to levels of oxytocin in cerebrospinal fluid, which bathes the brain.

New insight into the neuroscience of choking under pressure

Everyone knows the scene: a basketball player at the free throw line, bouncing the ball as he concentrates on the basket. It's a tight game, and his team needs this point. He regularly makes baskets from much farther away while avoiding defenders, but now, when all is calm, he chokes and misses the basket, and his team loses. Recent research from The Johns Hopkins University suggests that in situations like this, performance depends on two factors: the framing of the incentive in terms of a loss or a gain, and a person's aversion to loss.

High-speed 'label-free' imaging could reveal dangerous plaques

(Medical Xpress)—Researchers are close to commercializing a new type of medical imaging technology that could diagnose cardiovascular disease by measuring ultrasound signals from molecules exposed to a fast-pulsing laser.

Swallowing a sponge on a string could replace endoscopy as pre-cancer test
